Existing outside the conventional S.F. music club/bar scene for over ten years, a performance space called simply FourFiveFiveTenth (455 Tenth Street -- the address) has become that city's most prolific venue dedicated to experimental music.
Appearances by talents like If,Bwana, Big City Orchestra, Caroliner Rainbow, Freshly-Wrapped Candies, and Holland's Vidna Obmana, to name but a few. Their keen balance of numerous multi-media projects makes them one of the Bay Area's most important collectives.
Cha Cha's was usually closed to minors (though occasionally they were allowed in or snuck in). This left the new teen hardcore bands like M.A.D. and the Young Alcoholics out of the running. Other than that, the club was fun and surprisingly flexible, hosting the first major appearances of such far-flung concept bands as Sordid Details, The Thongs, Big City Orchestra, and The Holy Sisters of the Gaga Dada. In retrospect, Cha Cha's might be considered the last dying gasp of the early Santa Cruz scene.
